The Moon is the most viewed object in the sky, the Sun being too bright to look at directly and the planets too far away. The Greeks deduced everything that could be learned about the Moon using only the naked eye, including that it has no light of its own but reflects that of the Sun. They understood the cause of eclipses and used the Earth's shadow on the Moon to conclude that our planet is a sphere and to calculate the size of both the Moon and the Earth. The invention of the telescope some two millennia later offered the opportunity for much greater understanding, but the early observers became sidetracked onto a dead end: First, they fooled themselves into believing that they saw evidence of life on the Moon, even the works of a civilization. Second, they became convinced that the craters of the Moon were volcanoes like those we have on the Earth. These wrong-headed beliefs took centuries to dispel. The origin of the Moon itself has proven an even more difficult question, but scientists have now closed in on the answer. They find that our placid and seemingly unchanging Moon was born in colossal violence as a planet the size of Mars crashed into the primordial Earth and flung off a blob that solidified to become our heavenly companion. Unlocking the Moon's Secrets follows these developments to show how science evolves, complete with misunderstandings, contentious arguments, difficult to relinquish assumptions, and shifting views as new facts come to light. Thanks to the work of generations of determined scientists, we understand our Moon, at last.

Charles Ernest Fay (1846?1931), the ?Mr. American Mountaineering? of his day, was chairman of the meeting that led to the foundation of the Appalachian Mountain Club in 1876. Thereafter he served several terms as that club?s president and was the editor of its Journal, APPALACHIA, for 40 years. In 1902 he was elected as the first president of The American Alpine Club, and reelected for a second three-year term. In 1917, he was elected president once more, thus becoming not only the Club?s first president but also its longest serving. During all this period he was Professor of Modern Languages at Tufts College in Medford, Massachusetts, where he shared offices with the junior editor ? albeit with a hiatus of 18 years between their respective occupancies. Allen Herbert Bent (1867?1926), a native of Boston, Massachusetts, started his life of scholarly research into alpinism by dropping our of college ? anything but a promising beginning. Soon, however, he began the serious study of the history of mountaineering, ultimately writing extensively on this topic. He became the first person elected to The American Alpine Club, during its days of ?exclusivity,? under the ?or the equivalent? clause of membership prerequisites, for he was never a serious alpinist ? always contenting himself with the study of its literature. Howard Palmer (1883?1944), a lawyer by training, inherited the management of his family?s mattress manufacturing business in New London, Connecticut. Starting in 1907, he compiled an enviable record of first ascents in the mountains of western Canada and in 1914 published the North American classic, MOUNTAINEERING AND EXPLORATION IN THE SELKIRKS. He served as editor of the Club?s first guidebook and several editions of its JOURNAL. He also furthered the organization as its secretary, a director and as its president. James Monroe Thorington (1894?1989), of Philadelphia, was an ophthalmologist by profession, following in the footsteps of his father. After the end of World War I, Roy, as he was known to his intimates, spent most of his vacation time in the mountains of western Canada and served as editor of the Club?s guidebooks to that region for several editions. A diligent student of alpine literature, he compiled a number of scholarly researches into the history of American alpinism, served many years as a director of the Club, one term as its president, then for 10 years as editor of the AMERICAN ALPINE JOURNAL, and gave the Club some of the most valuable items in its museum. In 2000, the UIAA gave its first award for research into the history of alpinism under the name of James Monroe Thorington. After graduating from Harvard in 1942, Andrew John Kauffman (b. 1921) the son of two distinguished American literary figures, spent his entire working career in various diplomatic capacities. Between State Department assignments in Washington, Paris, Managua and Calcutta, he spent weekends and holidays in the Alps and the mountains of Peru, Colombia, Alaska, Canada, and finally in the Karakoram, where he demonstrated a high level of acromania by becoming one of the only two Americans to make the first ascent of an 8000 meter peak. He also served the Club as a counselor and as vice-president and was elected to Honorary Membership. William Lowell Putnam (b. 1924) has been an official of the Harvard Mountaineering Club, the Appalachian Mountain Club, then The American Alpine Club and finally the International Association of Alpine Societies (UIAA), and has been honored by several other mountaineering societies. His major employment was in television broadcasting, but his heart remains in the mountains of western Canada. At this writing he is the sole trustee of Lowell Observatory in Flagstaff, Arizona. While many have wished for the opportunity, people have not yet read his obituary.
Charles Darwin’s On the Origin of Species is one of the most important and yet least read scientific works in the history of science. The Annotated Origin is a facsimile of the first edition of 1859, and is accompanied by James T. Costa’s marginal annotations, drawing on his extensive experience with Darwin’s ideas in the field, lab, and classroom.
In Mysteries of Terra Firma, James Lawrence Powell tells an engrossing three-part tale of how we came to understand the ground on which we walk, and how that ground holds the key to the greatest secrets of deep space and time. Naming his profound stories Time, Drift, and Chance, he tells of the three twentieth-century revolutions in thought that created the amazing science of Earth -- and of all planets to the edge of the universe. The riddle that drove the first revolution is obvious and yet in 1904 remained impenetrable: how old is Earth? An encounter between the imperious Lord Kelvin and a New Zealand farm-boy-turned-physicist, Ernest Rutherford, set the stage for the solution and launched a golden century of geology. As a result, scientists learned that if the 4.5 billion years of geologic time were compressed into a single twenty-four-hour period, Homo sapiens would have arrived only in the last second. The geological Revolution of Time reveals how long the ground on which we walk has existed, and how briefly we have trod that ground. In the early twentieth century, German meteorologist and polar explorer Alfred Wegener proposed a counterintuitive, heretical theory: that terra firma is not so firm; instead of being fixed in place, continents drift. In 1926, petroleum geologists convened in New York City to discuss Wegener's radical idea, where it was met with outrage and skepticism: "If we are to believe Wegener's hypothesis we must forget everything which has been learned in the last seventy years and start all over again," one attendee said. Forty years later, a new generation did exactly that. The Revolution of Drift, the second part of Powell's narrative, showed us how the ground on which we walk moves. Throughout geologic time, meteorites have incessantly bombarded everything in the solar system. Far from serene and predictable, the planets are ruled by random violence on an unimaginable scale. Once a mountain-sized meteorite flew through space, struck the Earth, killed the dinosaurs and two-thirds of all species, and spared the small hamster-sized creature that happened to be our ancestor. The chance of that happening again is essentially zero. So, the final revolution in Powell's history of a golden century of geology is the Revolution of Chance. Simply put, this revolution in thought has transformed our understanding of how lucky we really are. If we can learn so much from considering no more than the rocks beneath our feet, what will we learn when we begin walking on other planets? Mysteries of Terra Firma is both charming in its storytelling and staggering in its implications. Discovering the ground on which we stand is a fascinating journey into our past -- and our future.
This book recounts the life and achievements of Clarence King, widely recognized as one of America's most gifted intellectuals of the nineteenth century, and a legendary figure in the American West. King led landmark precursory surveys that positioned him to become the founding director of the U.S. Geological Survey, the most important government science agency in the nation.
Provides the tools needed to analyze and solve acid drainage problems Featuring contributions from leading experts in science and engineering, this book explores the complex biogeochemistry of acid mine drainage, rock drainage, and acid sulfate soils.

Over the course of the twentieth century, scientists came to accept four counterintuitive yet fundamental facts about the Earth: deep time, continental drift, meteorite impact, and global warming. When first suggested, each proposition violated scientific orthodoxy and was quickly denounced as scientific—and sometimes religious—heresy. Nevertheless, after decades of rejection, scientists came to accept each theory. The stories behind these four discoveries reflect more than the fascinating push and pull of scientific work. They reveal the provocative nature of science and how it raises profound and sometimes uncomfortable truths as it advances. For example, counter to common sense, the Earth and the solar system are older than all of human existence; the interactions among the moving plates and the continents they carry account for nearly all of the Earth's surface features; and nearly every important feature of our solar system results from the chance collision of objects in space. Most surprising of all, we humans have altered the climate of an entire planet and now threaten the future of civilization. This absorbing scientific history is the only book to describe the evolution of these four ideas from heresy to truth, showing how science works in practice and how it inevitably corrects the mistakes of its practitioners. Scientists can be wrong, but they do not stay wrong. In the process, astonishing ideas are born, tested, and over time take root.
On 4 June 1629, the Batavia, pride of the Dutch East India Company Fleet, was wrecked on her maiden voyage in a seemingly empty expanse of the Indian Ocean. The question “how did this happen?” led to 300 years of investigation by those curious to solve the enigma: what are corals and how are coral reefs formed?. Relying heavily on primary source material Part 1 traces the sequential evolution of scientific thought and practice as the author explores the way this evolution is reflected in the search for understanding corals. At each stage, answers lead to fresh questions that challenge investigators to solve the riddle and new branches of science emerge. Then, with the first enigma finally understood, a new enigma arose. Why are Reefs dying? Part 2 traces the range of problems that have emerged in the past 50 years as marine, ecological, reef and climate scientists attempt to put the pieces of the jigsaw together. Is there a new “canary in the coal mine” warning of the fate of the world as we know it if man’s impact on his environment continues unchecked?.
Winner of the Historic New England Book Prize (2009) Winner of the Henry-Russell Hitchcock Book Award (2010) Henry Austin's (1804–1891) works receive consideration in books on nineteenth-century architecture, yet no book has focused scholarly attention on his primary achievements in New Haven, Connecticut, in Portland, Maine, and elsewhere. Austin was most active during the antebellum era, designing exotic buildings that have captured the imaginations of many for decades. James F. O'Gorman deftly documents Austin's work during the 1840s and '50s, the time when Austin was most productive and creative, and for which a wealth of material exists. The book is organized according to various building types: domestic, ecclesiastic, public, and commercial. O'Gorman helps to clarify what buildings should be attributed to the architect and comments on the various styles that went into his eclectic designs. Henry Austin is lavishly illustrated with 132 illustrations, including 32 in full color. Three extensive appendices provide valuable information on Austin's books, drawings, and his office.
